The weird pattern of flaking in the paint on the head tube (never saw that before) might have resulted from a very sudden shock transmitted through the fork from a frontal impact. (Or maybe a previous owner carried a coiled lock on the handlebar that continually scraped that spot.)

One quick test: measure the diameter of the down tube near the head tube both vertically and horizontally. If there's a tube section where the horizontal diameter of the tube is greater than the vertical diameter, that would indicate a bend in the tube resulting from the frontal impact.

Maybe start another thread in Framebuilders and provide separate closeup photos of the junctions of the top and bottom head lugs with the top and down tubes, holding the camera level with each lug.

Edit: could also be that the bent-back fork crown angle is throwing me off on judging the down tube/head tube junction. I hope so.
I appreciate the input, I've been in QC for 45 years. 25 as an inspector, mostly metal fab, welding, machining, etc. and 20 as a Quality Engineer. One of my strong points is failure analysis. Trust me, there is no frame damage.
